Enter the travel lengths fot each axis (x 609.6, y 355.6, z 127). Press the bottom softkey 'exit' then press enter 999 enter. Then press the bottom softkey again when it's booted.

[nuzmeed]

now
X=610.000MM
Y=355.00MM
Z=127.00 MM

I press soft key of Exit than I press 999, than ENTER key, it seems to me the keys are not working properly because the Manual key is also not working . i have pressed several time enter key but no response.

when I press exit key, it says again "choose appropriate soft key", it does not show the next screen.

[bloke]

You have to press enter then 999 then enter again.

[nuzmeed]

yes dear I am doing the same.

the cursor is blinking at the position choose the appropriate soft key.

I pressed Enter 999 Enter . but nothing happens

[nuzmeed]

Its DONE

when I press x, y or z key it shows 1, 2, 3, and the num keys were not functioning well only no. 6 was working.

I took a chance to reverse the Ribbon cable of the key board.

than tried and its done.

thanks Bloke!

can you please tell me further how to make the backup of this software coz I have nothing. I and if possible Service Manual of it in pdf. format.

I am very Much Thankful To you Again.

best regards

Now there is another Problem!

the main problem or fault on this machine is , its Y axis was problematic.

when any job is placed. it works fine after 2 or 3 hours it damages from y axis.

i thought its cooling problem as this department is very hot.

i have placed a PVC 4" pipe from windows AC to Panel Fan.

after that the problem come now after 8 to 10 hours.

I have a feeling that may be in X, Y axis Card there is some kind of ADC chip has become week. can you please tell me which one this could be

is it ADC0803. ???? or any other IC ???

Swap the XY and ZSpin boards.

Write down all the jumper and switch settings for both XY and ZSpin boards. Then swap the EPROMs between them and re-do the switches and jumpers. The spindle doesn't use the DAC.
